Patented Aug. 1Q, 1920.

Original application filed April 13, 1917, Serial No. 161,875. Divided and this application filed March 27,

1919. Serial To all @l1/wm t may concern Be it known that we, GUsrAv SCHLATTER, residing at Steinach, Switzerland, Villa Ceranique, Rorschacherstrasse 1, and Gos 'rnv SEGIN, residing at Arbon, Switzerland, Rebenstrasse 41, have invented new and useful lmprovements in Regulating Devices for filtering-Carts, of which the following is a specication.

Our invention relates to a regulating device for watering carts, which comprises a regulating valve mounted to turn and to move lengthwise in the spraying head and operated by the pressure ot water, and a hand operated. control piston which brings about the longitudinal movement ot' the regulating` 4valve controlling the length of the spray. The width of the spray is set by turning the regulating valve, and this turning movement also is brought about by the pressure of water. To that end we provide another hand operated device which turns the regulating valve by means of a rotary valve being arranged in the casing of the regulating valve coaXially with the same.

Uur present application 'is a division of another application for Letters Patent filed by us in the United States Patent O'ilice on April 13, 1917, Serial No. 161,875, on which Letters Patent No. 1,302,227 were issued to us on April 29, 1919.

regulating device according to our invention is illustrated by way of example in the accompanying drawing. y

Figure 1 is a longitudinal section of the device;

F ig. 2 is a section on line CD of Fig. 1;

Fig. 3 is a section on line G l-l of Fig. l on an enlarged scale, and

Fig. 4 is a section on line E-F of Fig. 1.

In the spraying head 1 closed at both ends by covers 2 and 4G, are mounted two pistons or valves, the regulating valve4 and the control piston 5 which is litted into the valve 4 and sliding with a. water tight lit in the cover 2. 2liongitudinal yn'iovemcnt of the regulating valve 4 determines the length of the spray, and its rotation the width of the spray. The spraying head 1 1s provided on the left side with a number of 'spraying holes 9. rllhe control piston 5 is hollow and open at both ends. ln the center it is provided, symmetrically of its longitudinal through the cover 50 and axis, with two sets of slots 11, two recesses 12 and 13 and a groove 14 arranged in the center coperating with slots and cylindrical guiding surfaces oi the regulating valve 4, in which the control piston 5 is working.

By moving the control piston to the right or to the lett by means of the bell crank lever 41, 42, the regulating valve 4 is shifted lengthwise above the spraying holes 9, and the length ot the spray is thus adjusted. Tater passes through a breeches pipe 43 into two casings 44 and 45 cast on the spraying head 1. From Vthe casing 44 it reaches the spraying holes 9.

ln the center oitl the cover 46, closing the spraying head 1 on the right, is cast a pipe 47. In thelatter mounted a tubular projection 48 of a rotary valve 49 which works to the rightof the cover 46 in a separate chamber. The rotary valve 49 is so connected to the regulating valve 4 that the latter is positively `forced to rotate with it, but can move longitudinally independently oi' it. Any well known or approved expedient may be employed for this purpose, as :for instance,a longitudinal rib on one of these members, sliding in a mating longitudinal groove in the other member as hereinafter described. The chamber is closed by a cover 50. The cover 50 is provided with a chamber 51 communicating with the second water supply pipe 45 through a conduit 52, and has an inner tubular projection 58 which adjoins a water outlet pipe 10 leading to an open reservoir of the cart. The rotary valve 49 has in its interior a second rotary valve 54 which iits tightly into it. The spindle 55 or the said valve 54 passes to the outside can be turned by hand by means of a lever 56.

vThe rotary valve 49 comprises an outer casing 57, as shown in F ig. 3, and two dia-V metrically opposite hollow blades 58 and 459 projecting beyond the casing. F rom the casing of vthe spraying head l start two diametrically opposite bridges 60 and 6l eX- tending tothe casing 57. These bridges and blades 58 and v59 Vi'orrn in the vposition illustrated four chambers ci c 7 ,/v oi equal size.

llVithin 'the outer casing 57 the rotary valve 49 has an inner casing 62 in which is mounted-the second rotary valve 54. The latter has in cross section the shape of aV cross, see Fig. 3. One arm 63 is provided Y 9 situated at each end with trough-shaped projections 64, 65 and 66, 67 respectively, and the other arm 68 has at each end a lug 69 and 7() respectively.

The casings 57 and 62 are connected together by a number of ribs, next to which in one or in both casings are arranged slots. rlfhe walls of the blades 58 and -59 are eX- tended inward to the casing 62. Between their ends connecting together the casings in the form oiribs, are arranged in the casing 62 slots 71 and 72. At both sides of the ribs are arranged turther slots 78, 74,75 and 76 in the casing62, and slots 7 7, 78, 79 and 8O in the casing 57. Normally to the blades 58 and 59, between the casings 57 and 62, are provided ribs 81;I and 82, at both sides oi. which are arranged slots 82, 88, 84

Yand 85 in the casing 62.

ln the illustrated position of the parts, water passes from the casing through the conduit 52 and the chamber 51 of the cover into the blades 58 and 59, Jtrom the latter through the slots 71 and 72, troughs 64 and 67, slots 73 and 75 and slots 77 and 79 into the chambers d and 7. is the latter are closed by the liXed walls and 61, the valve 49 will rotate clockwise owing to the pressure of the water on the blades 58, 59. The water filling the chambers c and g escapes through the slots 80, 85 and 78, 83 into the interior of the rotary valve 54 and thence through the projection 58 into the pipe 10. The rotation of the valve 49 continues until the slots 71 and 72 have passed completely beyond the bridges between the troughs of the valve 54. From that moment yno water can escape trom the blades 58 and 59. Simultaneously with the closing et the blades, the lugs 69 and 70 cover the slots 83 and 85, so (that water in the chambers c and g is held back, and holds the valve 49. The regulating piston 4 coupled to valve 49, has now closed a number ci' spraying holes, and therefore the width oi. spray is correspondingly reduced. lf it is tobe reduced still more, the valve 54 is turned again, whereupon the slots 71, 72 etc. are opened again. rhis can be repeated until the blades 58 and 59 strike the partitions 60, 61. 'At that moment, the spray holes within the reach of the regulating valve, are completely closed. 1n order to open them again, the valve 54 is turned in the opposite direction, so that the slots 71 and 72 are brought into communication with the troughs and 66, and the chambers e and g are filled with water, while water from the chambers d and 7 escapes through the slots 77 and 79.

Rotation of the valve 49 is transmitted to the regulating valve 4 by a ring 86 mounted on the hub 48 and provided with two or more arms 87 and 88, see Fig. 4, which terminate in teeth 89 and 90 and engage with parallel guides 91 of the regulating valve 4, so that the latter has to take part in the rotation of thev valve 49, while being able to move lengthwise.

In order to enable the valve 49 to be positively rotated in the event of its jamming or failing to respond to the water pressure, the rotary valve 54 is provided at its front end with teeth 92 which can'engage with teeth 93 of the valve 49 it it should get jammed. rl`his insures the possibility et rotating the vvalve 49 under any circumstances, that is to say, of operating it manually, if it tails to respond to the water pressure.

`What we claim is:

1. 1n a regulating device for watering carts, the combination with a regulating valve mounted to move lengthwise and to turn in the spraying head and operated by the water pressure, longitudinal movement oi the said valve determining the length oi the spray and its rotation determining the width oi' the spray, of a hand operated control device etlecting the longitudinal movement, and of another hand operated device effecting the rotation of the regulating` valve, a second valve rotated by the water pressure being arranged in the casing of the regulating valve coaxially with the same, and connected to it so as to allow the regulating valve to move longitudinally independently of the rotary valve, but to participate in its rotation.

2. ln a regulating device tor watering carts, the combination with a regulating valve mounted to move lengthwise and 'to turn in the spraying head and operated by the water pressure, longitudinal movement ot' the said valve determining the length et the spray and its rotation determining the width ot the spray, oi' a hand operated control device eliiecting the longitudinal movement, and of another hand operated device effecting the rotation ot' the regulating piston, a second valve rotated by the water pressure being arranged in the casing` of the Vregulating valve coa-Xially with the same, said rotary valve comprising blades working in chambers of the valve casing, separated by partitions, a hand operated rotary valve being mounted in the said rotary valve and adapted to open and close the conduits supplying water under pressure to the chambers of the casing and again carrying it away from same chambers.
